Does anyone know if the MMI PROM on older Disk ][ controllers has the same
pinout as any of the 74S* programmable PROMs?  I'd like to read the contents,
but would prefer not to let the magic smoke out of my programmer.


According to my Xref databook, the 6309 has the same pinout as
DM74LS471 and N82S136N and a few others.


Thanks, David.  That's exactly what I needed!
